ADT7467
dbCOOL Remote Thermal
Monitor and Fan Controller
The ADT7467 dbCOOL controller is a thermal monitor and
multiple PWM fan controller for noise-sensitive or power-sensitive
applications requiring active system cooling. The ADT7467 can drive
a fan using either a low or high frequency drive signal, monitor the
temperature of up to two remote sensor diodes plus its own internal
temperature, and measure and control the speed of up to four fans so
that they operate at the lowest possible speed for minimum acoustic
noise.
The automatic fan speed control loop optimizes fan speed for a
given temperature. A unique dynamic T MIN control mode enables the
system thermals/acoustics to be intelligently managed. The
effectiveness of the system’s thermal solution can be monitored using
the THERM input. The ADT7467 also provides critical thermal
